[PATCH v2 bpf-next 0/2] security.bpf xattr name prefix

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Follow up discussion in LPC 2024 [1], that we need security.bpf xattr
prefix. This set adds "security.bpf" xattr name prefix, and allows
bpf kfuncs bpf_get_[file|dentry]_xattr() to read these xattrs.

[1] https://lpc.events/event/18/contributions/1940/

Changes v1 => v2
1. Update comment of bpf_get_[file|dentry]_xattr. (Jiri Olsa)
2. Fix comment for return value of bpf_get_[file|dentry]_xattr.

v1: https://lore.kernel.org/bpf/20241002214637.3625277-1-song@xxxxxxxxxx/
